J. G. GRIFFIN, Zoology Department, University of Tasmania [Received by the Editor, 20 April 1965.] Abstract A new species of Paromola is described and illustrated from a single adult male specimen taken in 50 fms. near Three Kings Islands. A key to the genus Paromola is provided. The new species is perhaps most closely related to the western Indian Ocean P. profundarum Alcock and Anderson. The affinities of one of the other two New Zealand thelxiopids, Latreillopsis petterdi Grant, are discussed. INTRODUCTION IN January 1963 a small expedition from the University of Auckland Departments of Zoology and Botany, led by Mr Alan Baker, now of Victoria University of Wel- lington Zoology Department, visited the Three Kings Islands, some 36 miles north- west of Gape Maria Van Diemen. The purpose of the expedition was to investigate the flora and fauna of these islands and although most of the effort in the marine sphere was devoted to the intertidal zone, a few offshore stations were worked. One of these yielded a rather large crab which was forwarded to me by Mr Baker and Professor L. R. Richardson. The specimen proved to be a male of a new species belonging to the Family Thelxiopidae (= Homolidae). Up to the present time this family has been known to be represented in New Zealand by Latreillopsis petterdi Grant and Latreillia australiensis Henderson, species originally described from south-east Australia. -

F. Davie Queensland Museum, PO Box 3300, South Brisbane, Queensland, Australia Email: [email protected] ABSTRACT. – An annotated checklist of the extant brachyuran crabs of the world is presented for the first time. Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

Building Trophic Specializations That Result in Substantial Niche
Journal of Anatomy J. Anat. (2017) doi: 10.1111/joa.12742 Building trophic specializations that result in substantial niche partitioning within a young adaptive radiation Luz Patricia Hernandez,1 Dominique Adriaens,2 Christopher H. Martin,3 Peter C. Wainwright,4 Bert Masschaele5 and Manuel Dierick5 1Department of Biological Sciences, The George Washington University, Washington, DC, USA 2Evolutionary Morphology of Vertebrates, Ghent University, Ghent, Belgium 3Department of Biology, University of North Carolina, Chapel Hill, Chapel Hill, NC, USA 4Department of Evolution & Ecology, University of California, Davis, Davis, CA, USA 5Department of Subatomic and Radiation Physics, Ghent University, Ghent, Belgium Abstract Dietary partitioning often accompanies the increased morphological diversity seen during adaptive radiations within aquatic systems. While such niche partitioning would be expected in older radiations, it is unclear how significant morphological divergence occurs within a shorter time period. Here we show how differential growth in key elements of the feeding mechanism can bring about pronounced functional differences among closely related species. An incredibly young adaptive radiation of three Cyprinodon species residing within hypersaline lakes in San Salvador Island, Bahamas, has recently been described. Characterized by distinct head shapes, gut content analyses revealed three discrete feeding modes in these species: basal detritivory as well as derived durophagy and lepidophagy (scale-feeding). We dissected, cleared and stained, and micro-CT scanned species to assess functionally relevant differences in craniofacial musculoskeletal elements. The widespread feeding mode previously described for cyprinodontiforms, in which the force of the bite may be secondary to the requisite dexterity needed to pick at food items, is modified within both the scale specialist and the durophagous species. -

Reptiles As Principal Prey? Adaptations for Durophagy and Prey Selection by Jaguar (Panthera Onca) Everton B.P

Jaguars head and bite features show KEYWORDS adaptations to durophagy (consumption of hard-integumented Dangerous prey; prey) that are very unusual within the genus Panthera. These saurophagy; Tayassuidae; include: thick canines, well-developed head muscles and a fatal Xenarthra bite directed to braincase or nape. These characteristics have been previously considered an adaptation for the consumption of rep- tilian prey, whose thick integument poses a challenge to preda- tion. Although causation of any trait as result of natural selection is hard to demonstrate with ecological evidence, its consequences can be suggested and predictions made. Here, through a review of the literature on jaguar predatory habits, we tallied the evidence for saurophagy against environmental characteristics correlated with jaguar predation on reptiles. We offer a new explanation for the presence of those traits, based on the selection patterns, prey abundances and main predation habits over the geographic range of the jaguar. -
How to Become a Crab: Phenotypic Constraints on a Recurring Body Plan

For over 140 years, convergent evolution of the crab-like body plan (with a wide and flattened shape, and a bent abdomen) at least five times in decapod crustaceans has been known as ‘carcinization’. The repeated loss of this body plan has been identified as ‘decarcinization’. We offer phylogenetic strategies to include poorly known groups, and direct evidence from fossils, that will resolve the pattern of crab evolution and the degree of phenotypic variation within crabs. Proposed ecological advantages of the crab body are summarized into a hypothesis of phenotypic integration suggesting correlated evolution of the carapace shape and abdomen. Our premise provides fertile ground for future studies of the genomic and developmental basis, and the predictability, of the crab-like body form.

17 the Crabs Belonging to the Grapsoidea Include a Lot Of
17 SUPERFAMILY GRAPSOIDEA The crabs belonging to the Grapsoidea include a lot of ubiquitous species collected in the mangrove and/or along the coastline. As a result, most of the species listed here under the ‘Coastal Rock-rubble’ biotope of table 2b could be reasonably listed also with marine species. This is particularly true for the Grapsidae: Grapsus, Pachygrapsus, Pseudograpsus, and Thalassograpsus. FAMILY GECARCINIDAE Cardisoma carnifex (Herbst, 1796).
